PostGIS

Spatial Database

PostGIS spatially enables the popular PostgreSQL object-relational database, allowing it to be used as a back-end database for geographic information systems (GIS) and web-mapping applications.

PostGIS is stable, fast, standards compliant, with hundreds of spatial functions and is currently the most widely used Open Source spatial database. PostGIS is used by diverse organisations from around the world, including risk-averse government agencies and organisations storing terabytes of data serving millions of web requests per day.

Database administration is available for desktop and the web via pgAdmin, phpPgAdmin, and others. Data import/export can be done by command line tools (shp2pgsql, pgsql2shp, ogr2ogr, dxf2postgis) or from desktop and web GIS clients. These clients can also map and manipulate PostGIS spatial data tables.
